Water Ring Vacuum Pump Advantages

The appearance of vacuum pump brings convenience to many industries, especially in industry. Water ring vacuum pump is one of the products with simple structure, low manufacturing precision and easy processing.liquid-ring-vacuum-pump-type

Water-ring vacuum pump (hereinafter referred to as water-ring pump) is a kind of coarse vacuum pump. The maximum vacuum it can obtain is 2000-4000Pa. The vacuum degree of the unit composed of water-ring vacuum pump and vacuum pump can reach 1-600 Pa.

 water ring vacuum pump advantages:

1. Simple structure, low manufacturing accuracy and easy processing. The structure is compact, the speed of the pump is high, and the pump can be directly connected with the motor without slowing down the installation. Therefore, with a small structure size, it can achieve a large amount of exhaust gas and occupy a small air area.

2. Compacted gases are essentially isothermal, i.e. the temperature varies little in the process of compacted gases.

3. Because there is no metallic abrasion in the pump chamber, there is no need to stop smooth inside the pump, and the wear is very small. The sealing between the rotating part and the fixing part can be accomplished directly by the water seal.

4. Average inspiration, stable and reliable work, simple operation and convenient maintenance.how-does-the-liquid-ring-vacuum-pump-work

Water Ring Vacuum Pump Daily Maintenance

In the normal work of water ring vacuum pump, packing should be pressed regularly. If the packing can not guarantee the required sealing performance due to wear, new packing should be replaced. If mechanical seals are used and leakage is found, the dynamic and static rings of mechanical seals should be checked for damage or aging of auxiliary seals. If the above situation occurs, new parts need to be replaced.

When special sound occurs, the pressure plate on the two end covers can be removed to check whether the two end faces of the impeller are scratched with the distributor or whether the exhaust valve plate is normal.water-ring-vacuum-pump-type

In normal work, attention should be paid to check the work and lubrication of bearings. The temperature (bearing and outer circle) of bearings is generally higher than the ambient temperature by 15 to 20 degrees Celsius. The maximum temperature should not exceed 30 to 35 degrees Celsius. That is to say, the actual temperature at the outer circle of bearing rack of water ring vacuum pump should not exceed 55 to 60 degrees Celsius. The bearings in normal work should be oiled 3 to 4 times a year, cleaned at least once a year, and moistened. All the lubricants are replaced.water-ring-vacuum-pump-application

Water Ring Vacuum Pump Solutions to Leakage

Water ring vacuum pump leaks for different reasons, its treatment methods will also be different, not to identify a cause of leakage, under different circumstances, the leakage should be solved in accordance with the appropriate method, then we may have five reasons for leakage for you to briefly introduce its treatment methods.

1. Leakage of machine in operation

If a machine is found to be leaking, it must not stop its work immediately. It should be kept at the lowest stable speed, and water should be added to the inner side of the cooling system at the same time. (Note: when opening the nozzle cover, a cover should be placed above it to prevent steam from burning), so that the engine can cool down, run at a short time and at a slow speed, and drive to the nearby concealed place for removal.

2. Water leakage due to breakdown of vacuum pump shell

If the vacuum pump shell breaks suddenly and leaks water, or the internal parts are damaged and lose the pump function, the relevant parts can be replaced as appropriate to eliminate the failure.

3. The water ring vacuum pump itself is seriously damaged.

If the pump is badly damaged and there is no repair condition on the way, the inlet and outlet pipes of the stainless steel vacuum pump can be directly connected to make full use of the natural circulation of hot and cold water to temporarily keep the engine at normal temperature; or an inner tube or bucket can be used as a container to firmly fix it, and then two rubber pipes are introduced from the container, one of which is connected to the engine's water inflow. On the mouth, the other one is connected to the outlet of the engine. The other end of the two pipes is inserted into the container, and the rubber pipe should be fixed firmly.

4. Leakage due to cracks only in pump housing

If only the shell of the water ring vacuum pump cracks and leaks, the cracks can be cleaned up and then bonded with adhesives. In order to meet the emergency, egg white and cement can be mixed into a sticky mass and applied to the cracks, which can be used after several minutes of solidification.

If the water seal of the water ring vacuum pump leaks slightly due to improper sealing, but the wear is not serious, a sand cloth can be laid on the glass plate or flat plate, and the sealing surface of the water seal can be grinded flat, or the water seal of bakelite can be turned over and used again. However, it should be noted that the contact surface between the water seal and the pump body should be ground to ensure its sealing performance.

Roots Vacuum Pump Installation

Roots vacuum pump installation is best by professional people to install, if the conditions are limited, we need to read the instructions carefully, and then install, compiled for you to collate some useful information, to understand it.

1. Roots pumps should be installed in dry, ventilated and clean places.

2. The pump should be installed horizontally. The gap between the pump and the wall or other objects should be at least 300 mm. The oil window part of the pump should leave room for easy observation of the oil level.

3. Attention should be paid to the motor turning when turning on the power supply. Seen from the tail, the turning of the motor shaft should be clockwise. The specific operation steps are to turn on the three-phase power supply of the motor, point the motor start button, check whether the turning is correct or not. If the turning is opposite, change any two of the three power terminals.roots-vacuum-pump-supplier

4. The pipeline of the pump and the pumped container should be clean, dry and leak-free. The diameter of the pipeline should be as small as possible as the inlet of Roots pump. The length of the pipeline should be shorter so as to reduce the pumping speed loss. There should be no leakage at the connection of the pipeline.

5. When the exhausted gas contains dust or granular substances, an appropriate intake filter should be installed at the inlet of the pump to avoid damage to the Roots vacuum pump by inhaling dust or granular substances into the pump chamber.

These aspects should be paid attention to in the installation of Roots vacuum pump, and the pumping speed and limit pressure of Roots vacuum pump should be taken into account. The influence degree of Roots vacuum pump varies with the structure of the filter.roots-blowers-price

single stage rotary vane vacuum pump structure

As a single-stage rotary vane vacuum pump, there is only one studio, which is mainly composed of stator, rotor and rotary vane. As shown in the figure below. The rotor is eccentrically placed in the stator. There are two rotating blades in the rotor tip, and a spring is arranged between the two rotating blades. Relying on spring elasticity and centrifugal force when the pump rotates, the rotary blade is close to the pump wall.rotary-vane-vacuum-pump-supplier

Generally, the pump chamber is divided into three parts: the space from the intake bamboo to the rotary blade is called suction (space, the space attached by the two rotary blades with the pump wall is called expansion and compression space; the space from the exhaust valve to the rotary blade is called exhaust space. If the rotary vane is in the vertical filling position, the pump chamber is divided into two parts (that is, the suction space and the exhaust space). But no matter where the blade is located, it always separates the intake valve from the exhaust port. The purpose of the exhaust valve immersed in oil is to prevent air reflux into the pump. In order to prevent the sudden power outage of vacuum pump oil flowing back into the vacuum container, a solenoid valve is installed on the intake pipe. Once power outage occurs, the solenoid valve blockades the passage. When the pump is opened, the solenoid valve sucks up and the passage opens.rotary-vane-vacuum-pump-structure
